To'all whom. may concern'. v Be i` known that I, BENJAMIN A. GRAMM,

residing at Lima, inthe connty' of Allen and State of Ohio, haveinvented. certain new and useful Improvements in Auxiliary.

1 Driving Mechanisms, of which the following is a specication,vreference a being had to the accompanying drawings.

This invention relates to improvements in auxiliary driving mechanisms"actuated byV automobile transmission mechanism; and an object of' thisinvention isfto provide an .auxiliary driving mechanism by which powermay be taken from the main driving gear of the transmissionand used fordriv" ing secondary mechanisms (-such` as hoists,

pumps, Winches, etc.) that maybe vmounted onthe automobile or motortruckof which the transmission forms apart.

` In the drawings illustrating the principle of this invention vand thebestmode now knownl tome of. applying that piiinciple,

Figure 1 is a -plansof an automobile transmission having my newAattachment fastened thereto, partly. section Aand part of the cover ofthe transmission case being omitted for clearness;V Fig. 2 is a sectionon the line 2-'2' of Fig. 4,' this sectionv beingl on a -scale smallerthan the latter figure; Fig. 3 is a section on the line 3-3 of Fig.4;and Fig. 4 is a section onthe'line @1 -4; .ofFig' 3;

In the transmissioncase a, thereis journaled a rotatable shaftgb onwhich is mount# ed 4fast a spur gear 'c 'th'at meshes with'a smallergear or pinion d ast`ontheengine (or motor)- shafte. `When itisdesiredto.

drive the transmi'seien-shaft]c directly from vthe motor-shaft e, theclutch-member -f, which. is keyed. or splined to the tra-ns-`missionshaft f,-is thrown-Sinto .engagement with the .clutchme'mber g'mountedfast upon thismotor (or engine) shaft e. Of course,

this idler-gear 71. meshes withan idler-gear i that is likewise mountedon a ball-bearing* .from the driving-shaft e. Thus it is p'osf i 2, 3and 4.). f

when the clutch-members It', k, are. in.

As is clearly indicated by the'dotted lines '-drivin e rear end of thecasing o instead of the front vend thereof; therefore, it results thatthev propellershaft p may be driven ing 0. Since this mechanism isdrivenfrom ltransmission mechanism -hereinbefore 'de` l i v 8. in 'Figs 1,-2and 3, the shaft of the auxiliary mechanism may b e made to project a. Ifrom either the front or the rear of the cas- Y 'the transmissiomit isentirely 4practicable so to arrange the parts that, as is herein shown,

'the two form together a complete unit that495 i I is oil-tightanddust-proof.A I am aware of'thepatent granted Samuel W. Luitwieler, No.1,023,084, April9, 1912,

In themechthe clutch-member fslidablelengthwise -of the latter 'shaftand is,^by reason of'being keyedor s plined thereto', rotatable theifevvithr However', the clutchmembersf?, g, .have nov Vnecessary part in the operation of the aumliarydriving mechanism herein described..
